IMPRCVEMENT IN HANDLES FOR CROSSCU'T-SAWS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, WILLIAM CLEMsoN, ofMiddletown, in the count-y of Orange, in the State of New York, haveinvented anew and improved Mode of Attaching Handles to Crosscut-Saws;and I do hereby declare that the following is a full and exactdescription thereof', reference being had to the accompanying drawings,and to the letters ot reference marked thereon.

My invention consists of' the combination of the devices used by whichthe handle is tirrnly attached to the saw.

To enable others skilled in the art to make and use my invention, I willdescribe its construction and operation.

In the drawings- Figure 1 represents a section of a s aw with the handleattached; Y

Figure 2 is a cross-section of same;

Figure 3 is a view of the upper end of the ferrule on the handle; and

Figure 4 is a section of the inclined slotted clampblock.

A represents a part of the blade of a common crosscut-saw.

E is a looped or slotted screw-shank, having the saw A inserted in theslot.

D is an inclined slotted clamp-block, having a hole in its centre,through which shank E freely passes, and is made higher on one side thanon the other, to tit the taper ofthe saw, and has a concave slot, ,onits inclined end, which tits closely'upon the back of the saw.

C is a fel-rule, with a solidend, c, in which is a female screw, andinto which the screw on the end of the `shank enters.

The slot a in clamp-block D is made concave, to insure a close fit outhe back of the saw, at its outer contact with the saw, as seen in redlilies, as seen Vin dotted lines, in lig. l o

The ribs d, on the inside of the ferrule, prevent the handle fromturning in, and without turning the nut c on the screw-shank.

Then the ferrule C is placed on the handle B, the screw-shank is passedthrough clamp-block D, and is then screwed into the nut-part of theferrule C, the clamp-block D turnedv so that the inclined side fits thetaper of the back of the saw, which is inserted iu the loop-part of theshank, and the slot in the block embraces the back of the saw, as 'seenin iig. 1, and the handle B is turned down upon the screw-shank E, theblock is forced upon the saw, and the handle is firmly xed to the saw;and 4by only turning the handle in the opposite direction, the handle isreleased, and can be taken from the saw.

This construction and arrangement of devices make an attachment that ischeap, easily operated, and that can be depended upon for security, asWell as durability, and not likely to get ont of order, and admits of aconsiderable variation 0f width iu saw-blades, and allows/the handle toalways be at right angles with the saw.

I am aware that slotted screw-Shanks, inserted in handles, have beenused forat-taching handles to saws; such slotted screw-shanks or hooks Ido not claim. ,Nor do I claim for the ribs on the inside of the ferrule,as such ribs are old and in use; but having described my invention,

W hat I claim, and desire to secure by Letters Patcnt, is

The combination of the slotted screw-shank-E, inclined slotted block I),ferrule C, and handle B, when constructed and arranged to operatetogether, in the manner and for the purpose described.

XVM. CLEMSON.
